CARPET-CLEAN ING MACHINE.

Be it known that LJULES DEHoN, citiff-zen of the United States, residing in the city Zand county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Carpet-Cleaning Machine,- of which the following is aspecification.

This invention relatesto the art of cleaning carpets, rugs and otherfabrics or textiles, by operations of beating and scrubbing which involve thev use of brushes, beaters, air-ejectors, dust-sucking, and other' devices for effecting a cleaning operation without injury to the article to be cleaned.

tion is an improvement upon an invention made by me which forms the subject-matter of United States Letters Patent N o. 1,196,527, dated August 29th, 1916, to which vreference' isl to be made,-aud it compreliends particularly special devices by means of which the carpet is connected with the carrying apron A by which it is conveyed and caused to be presented to the devices which effect its cleaning',and also comprehends other devices by means of which the carpet is held against the apron during its travel, and still other de# vices by means 0f which the cleaning brushes are maintained in operative contact with the apron.

The general elements which constitute the machine of my patent referred to and which are embodied in my presentl machine, are referred to in my patent and as general elements per se are not herein claimed by me. For the purpose of illustrating my inveiition, I have shown in the accompanying drawings aV certain type and embodiment of it which is at present preferred by me because in practice it ha-s given satisfactory and reliable results. It is to be understood,

however, that the various components in which my present invention is shown as einbodied can be variously arranged and that my invention is not', therefore, limited to the precise arrangement which is typified in the construction shown in the` accompanying drawings and hereinafter described.

Obviously, modifications of' the specific devices represented, described and claimed,

may be easily effected.

Referring tothe drawings The base frame o f the machine is of any perspec- 4desired construction but preferably of structural iron members to which the .numeral 1 is applied, and which are conveniently con-y nected with a bedplate 2, so asV with. it to form adrip tank to receive vthedrippage of brush to forma framework relatively to Ywhich the apron as an entirety and the brushand cleaning devices are m0unted.`

The endless apron or carpet carrier 6 is framework', Tand is mounted upon endless carrying sprocket chains 7, two or more. of 'which in parallel relationship serve as the medium of 'its `support and travel.

of any preferred construction but conveniently composed of slats, is transverse of the vInl the apronorganization represented,

five carrying sprocketwheels 8,' 9, l0, 1l

and12 are shown as being mounted upon rotary shafts 8*, 9X, 10X, 11X and 12X which are housed in bearings of any preferred type, for instance such as 13, Fig. l1. The driving of the apron in the direction of the arrows upon the drawings, is conveniently effected by sprocket wheels on said rotary shafts, of any preferred'typ'e, driven primarily by the power wheel 14.

15, 16 and 17 designate cylindric cleaning brushes,18, 19 and 20, cleaning fluid ejeci in Figs. 5 and 8,

cleaned, and 15", 16 and 17 X before a brush shaft of', for instance, the brush 16,

which shaft is mountedI in a bearing 22 formed upon the end of a radial lever 23 fulcrumed on a rotary shaft 24 housed in .the bearing bracket 25 and conveniently supported from a pillar 3,4- which shaft, beingA of course driven by one of .the motors, as 16", carries the driving pinion ,26 which meshes with the drivenv pinion 27 on the brush shaft 21.`

From the free end of the brush lever 23 depends acounterweight 28 which tends to maintain the brush 16 in such contact with the carpet controlled by the adjusting screw 29 which is Vmounted on the frame of the machine, as shwn in Fig. 5, and bears upon the inner end of said brush' lever 23.

30 designates a rotary beater of thecharacter of that fused in the machine of my patent referred to,the arms of which beat upon the carpet 31 or otherfabric to be cleaned, and', loosening the dust'from the meshes or ihterstices of its web, beat it through the .sievel 32 which incloses the upper opening of the suction-trough '33 equipped with a suction fan or blower 34, the outlet of which is. 35 as typically illus tratedin Fig. 2.

The fastening mechanism which I employ for fastening'or securing the free end of the carpet on fabric to be cleaned tohthe apron, is illustrated in Figs. 2, 3 and 4 and is of the following construction. 36 is a bar of channel iron` of a typical concaveV on hollow form, preferably such, for instance, as is clearly illustrated inFig. l

4, which '.is of the length of one of the slats of the 'carrying apron, and in its application to said'. apron takes the place of, that is to say is substituted for, one of theislats',.-be-, ing conveniently connected with the carrying chains of the apron in the samemanner as are the slats themselves.

In its application to thcapron the chanlnel iron faces outward as shown in Fig. 2, that is to say, itsV open face is exterior of the apron as an entirety, and its flat back faces inwardly. It constitutes a combined slat and receptacle, so to speak, which is adapted to contain a carpet fastening means of special construction, namely a bar of angle iron 37 which is secured toit by bolts 38, and which faces outwardly so as to be adapted to receive beneath its lower member the lower limb' of an angle iron which I term the carrying iron 'or bar 39.

Both'the Aangle iron 37 and the carrying iron 39 are preferablyv of the length ofthe channel iron 36 so that in their applied relationship to said channel iron they it within, and extend longitudinally throughout, it.

Supported on the" lower member of the channel iron 36 and extending right angu larlypreferably up to the rear face of said channel iron, are a plurality of lugs 40, disposed preferably in groups at different distances along the interior of the channel iron, which receive and support the lower member ofthe carrying iron 39 when the latter is introduced within the channel iron and between the lower member of the carrying viron 39 and the lugs aforesaid, as will be'best understood from Fig. 4. f To the front face member of the carrying ^iron 39 is attached ,by a rivet 41, o r equivalent fastening, a flexible connecting web 42 which is of'equal length with the .length of the channel iron, that is to say, of a length about equal to the breadth of the apron, and to this connecting web 4which may bevof canvas orA kindred flexible material, I connect the carpet 31 to be cleaned, by attaching eyes 43, Figs. 2 and 3, which are simply attaching devices of any preferred., character by means of which the free end of the carpet can at will be connected with or detached from the connecting 'web 42.

Longitudinally` extending within the channel iron 36 is an operating rod 44, housed for* end-for-end movement in slide `bearings 45` within the channel iron, and adapted to be thrown to the right or `the left vas shownin Fig. 3 by an operating handle 46 extending through an elongated yaperture 47 through the rear wall of the channel iron, which handle is adapted to be by the operator' by simply takl manipulated ing hold of it and moving it transversely 1n or out from the side of the apron.

48 is anvelbow lever fulcrumed .at 49 on itsvertical member extended betweenV two bosses 50 and 51 xed on the operating rod 44, and, therefore, adapted to bel encountered by either one of themand according .125* the rear face of theangle iron 37, and as to, f

to the direction of movement of the operating rod 44 to occasion the yelevation or dethe angle iron 37, and at its other or free end slotted to permit the shank of the locking latch 52 to pass through it, as best slown in Figs. 3 and 4.4

In practice, I employtwo or more .of these `locking latches 52 andbell `crank levers 48,

connected with and operated by the aforesaid rod 44,'and in the attachment of the carrying iron 39 and its connectingweb 42,

th'e boltsA and `bell-crank 4levers are in the position represented in -dotted lines in Fig. 3, and when the attachment 'has been completed are in the posit-ion represented in f ull lines in said Fig.

When the rod 44 is moved in one direction by the handle 46, the latches 52 are raised through the' slots 54 and the carrying iron 39 is released of the holding action of said latches, and said angle iron may be drawn out of the channel iron or bar 36, and with it the web 42. Then the carpet `can be disconnected from said web after which a fresh piece of carpet may be connected with said web, when the angle iron 39 is again introduced into the channel bar 36, and the rod 44 operated wherebythe lever'45 lowers the latches 52 and locks said iron'39 with the iron- 37. The piece, of carpet may besubjected to the actionof the beaters 30 over the trough 33 and then carried down around the machine by theendless apron during which time it will be subjected to brushing, the fluid-.cleaning material, squeezing and othermanipulation as before.

. This specic device as an entirety is one of simplicity and reliable operativeness, and

serves as a means' for quickly and convenvactive elements to operate upon the carpet iently attaching and-detaching the carpet to and from the endless apron.

In Figs. 2, 6, and 9 I have represented a squeezing device-which is the last of the after the Vbeating devices, the brushing mechanism and the washing or cleansing huid Amechanisms have operated upon it.`

"In` this device 58 represents a squeezing web or strip of flexible material such, for j instance, as rubber cloth, which is held withfina collar-like head 59, preferably cylindri- I' 7, form and formed with. radially and outwardlyvextending parallel lilangzlges 60, be-

introduced and retained by bolts.

tween which the inner edge of said web 58 is length than y Letters Patent,- is 1 The web extends transversely of the Ina- 'chine to a length preferably equal tothebreadth of the traveling apron. The head 59 is" of equal, or preferably slightly greater `-the web and at its ends is lixedly secured to balance levers 61, fulcrumed at 62 tothe framework, and having theirfree ends which extend beyond the fulcra provided with-weights 63.

Obviously, the construction and mounting of this squeezingdevice is such as to insure a'constant pressure of the web against lthe carpet in its travel on and with the apron and a constant resultant expression of all excess cleansing fluid or water from lthe carpet.

, In Fig. 7, Ihave represented a pressure roll 64, which is adjustable to vhold the car- *A pet against'the endless apron-to prevent sagging of the former in the travel of the latter long or a little longer than the breadth of the. aprem-and its trunnions 65 have4 at eachend bearings in suspended links 66 which are pivoted to adjusting bolts 67 connected with the frame-work and adapted to be set in adjustedvertical position by lock nuts 68. The direct connection and support ol this pressure roll relatively to the-framework is through carrying arms 69,y as clearly shown in Fig. 7. A.

The brushes l5, 16 and 17 have each their own indiivdual motorsso as lto enable them to be run at the same or dilerent'de'grees of speed for purposes requiring 'thesame.

each brush has its own adjustmentso that it can be set to cause theproper action on,

the carpet at its distinctive place of contact without regard to the other brushes.y I Having'A thus described 1 my invention,
